Nine people have been killed in Gaza in fighting between militant group Hamas and allies of its rival, Fatah. Reports said up to 88 people were hurt after Hamas officials surrounded a house allegedly linked to a bombing that killed five Hamas men and a girl. Israel has allowed nearly 200 Fatah members, including at least one key clan member wanted by Hamas, to cross the border, Israeli officials said.
Saturday's violence was the worst in a week of tit-for-tat operations. The latest operation was also among the most sweeping since Hamas seized power in Gaza from the Fatah-led Palestinian Authority in 2007. Dozens of people have been arrested in Gaza and the West Bank in the past week during Hamas and Fatah operations against each other's supporters.
